Are we about to experience the same thing again? This is a very long article and people will lose interest so....here's a youtube synopsis.
A glacier the size of Florida is on track to change the course of human civilization.
Thwaites glacier in West Antarctica is enormous and is often referred to as the most dangerous glacier on Earth. It has also been dubbed the doomsday glacier. The glacier holds two feet of sea level but more importantly, it is the “backstop” for four other glaciers which holds an additional 10-13 feet of sea level rise. When Thwaites collapses it will take most of West Antarctica with it. This is not new information for those of us that follow the science. For example, Eric Rignot in 2014, stated that the loss of West Antarctica is unstoppable. You can listen to an excellent interview from 2019 between Rignot and Radio Eco-shock on Antarctica.
